Abstract

We briefly overview our recent results on nonequilibrium interactions between neighbouring electrically isolated nanostructures. One of the nanostructures is represented by an externally biased quantum point contact (drive-QPC), which is used to supply energy quanta to the second nanostructure (detector). Absorption of these nonequilibrium quanta of energy generates a dc current in the detector, ...
